Upper Mississippi Bluff-to-Bluff (MN, WI)
The Driftless Area is a region of unique geological significance in the Midwestern US having never been covered by ice during the last ice age. Unlike the rest of the mostly flat Midwest, the landscape is characterized by steep hills, forested ridges, and deeply carved river valleys, and is bisected by the Mississippi River. This route is located in La Crosse, WI, in the heart of the Driftless Region and spans the largest river in the United States.
